Just released:
SNORTⓇ Subscriber Rule Set Update for Sept. 11, 2018

Today, we welcome the introduction of the newest rule release from Talos. In this release, we introduced 46 new rules, 20 of which are shared object rules. There are also eight modified rules, of which four are shared object rules.

This release covers Microsoft Patch Tuesday. The monthly security update from Microsoft disclosed dozens of vulnerabilities across multiple products, including the Internet Explorer and Edge web browsers, as well as the Chakra scripting engine. If you would like to know more about these vulnerabilities, check out Talos' full blog post on Patch Tuesday here.

Our rule update also adds new protections against the MysteryBot malware, a family that's been spotted on Android platforms.
